The coupling constant of a0-->rho-gamma and f0-->rho-gamma decays are
calculated using 3-point sum rule. We estimate the coupling constant
g_a0-rho-gamma and g_f0-rho-gamma which are an essential ingredient in the
analysis of physical processes involving isoscalar f0(980) and isovector
a0(980) mesons.
